Windows PC

Opera One version: 133.0.5932.24

Opera is crashing in a loop on startup. It opens, closes, and repeats. I cannot get it to stay open at all.

What happened:

• This started after a recent Opera update in early July 2026.
• I closed Roblox with Alt+F4 right before I noticed the problem, but Opera is the app that is now crashing.
• Reinstalling Opera did not fix it.

What I found:

• The faulting module in the crash dumps is opera_browser.dll
• Exception code: 0x80000003
• The same crash appears in multiple recent dumps

Expected behavior:
Opera should open normally and stay open.

Actual behavior:
Opera opens and immediately crashes/restarts in a loop.

I have profile backups and crash dumps available if needed.
